this was one of the earlier attempts to tell what happened, john hersey's 1946 new yorker piece, "hiroshima"
here's a little intro page that's most self-promotion for the writer of it (not hersey) but which is interesting nonetheless:
"Hiroshima" by John Hersey
here's a link to the full text of hersey's piece.
Full text of "Hiroshima"
just so we're all in the same place in terms of what's being talked about here.
later, things like this helped frame what happened at hiroshima internationally (marguerite duras/alain resnais, 1959)
infotainment:
Hiroshima mon amour (1959)
and tied it up with ambiguities of memory/memorialization that center on world war 2.
which was kinda fucked up.
the whole thing. nothing worse that a nation-state level techno-science shaped war in which everyone feels justified and in which racism plays such a prominent role. it's kind of a psychotic place to get to that enabled thinking that dropping nuclear weapons on these cities was humane. and there was a school of thought that ran that way: the invasion of japan scenarios and the nukes as a way to avoid them.
